```Python
UserInDB(**user_in.model_dump())
```

...because `user_in.model_dump()` is a `dict`, and then we make Python "unpack" it by passing it to `UserInDB` prefixed with `**`.

So, we get a Pydantic model from the data in another Pydantic model.

#### Unpacking a `dict` and extra keywords { #unpacking-a-dict-and-extra-keywords }

And then adding the extra keyword argument `hashed_password=hashed_password`, like in:

```Python

In the previous example, we were returning a `dict` from our dependency ("dependable"):

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[9] *}

But then we get a `dict` in the parameter `commons` of the *path operation function*.

And we know that editors can't provide a lot of support (like completion) for `dict`s, because they can't know their keys and value types.

    command: |-
      /bin/sh -c 'set -euo pipefail;
      /usr/local/bin/entrypoint.sh gaussdb &
      counter=1;
      while [ "$$counter" -le 20 ]; do
        if su - omm -c "gsql -U omm -d postgres -c \"SELECT 1;\""; then
          echo "Creating database gorm...";
          su - omm -c "gsql -U omm -d postgres -c \"CREATE DATABASE gorm DBCOMPATIBILITY '\'PG\'';\"";
          echo "Database initialized successfully";
          break;

	STATUS=$?
	if [ $STATUS -eq 0 ]; then
		DATA_DRIVE=1
	fi

	if [ $DATA_DRIVE -eq -1 ]; then
		# Check for existence of file in erasure set 2
		docker exec resiliency-minio1-1 /bin/sh -c "stat /data5/test-bucket/$DIR/$FILE/xl.meta" >/dev/null 2>&1
		STATUS=$?
		if [ $STATUS -eq 0 ]; then
			DATA_DRIVE=5
		fi
	fi
	echo $DATA_DRIVE
}

It declares an optional query parameter `q` as a `str`, and then it just returns it.

This is quite simple (not very useful), but will help us focus on how the sub-dependencies work.

## Second dependency, "dependable" and "dependant" { #second-dependency-dependable-and-dependant }
